Data Recovery from DVD

Ok, long story short, my computer was consumed by spyware. Processes like “The Matrix Has You” were seen from the process manager, which was disabled until I got it working. Anyways, having tumbled with my computer for a good four hours, picking away at the infections, I’m just like F’ it! Backed up all my data on 5 DVDs and reformatted the windows drive. Nice and clean install. When I went to unload my backed out data, the first DVD refuses to be read [Not Responding]. The first DVD has all my important shit on it. Including my Ultima 5 - Lazarus SAVE (30 hours in!!!) I’m not fimilar at all with data recovery techniques so if anyone has any idea how I can get the data from the defected DVD, I’d appreachiate it.
